BaseX [1] is both a light-weight, high-performance and scalable XML Database and an XPath/XQuery Processor with full support for the W3C Update and Full Text extensions. It focuses on storing, querying, and visualizing large XML and JSON documents and collections. A visual frontend allows users to interactively explore data and evaluate queries in realtime (i.e., with each key click). BaseX is platform-independent and distributed under the free BSD License (find BaseX GUI more in Wikipedia [2]). This documentation is based on BaseX 7.1.1. Features that have recently been changed are flagged in red (e.g.: Version 7.2). Getting Started The Getting Started Section gives you a quick introduction to BaseX. We suggest you to start with the Graphical User Interface as this is the easiest way to access your XML data, and to get an idea of how XQuery and BaseX works. Categories: Beginners XQuery Portal More information on using the wide range of XQuery functions and performing XPath and XQuery requests with BaseX can be found in our XQuery Portal. Categories: XQuery Developer Section The Developer Section provides useful information for developers. Here you can find information on various alternatives to integrate BaseX into your own project. Categories: Developer, HTTP, API Advanced User's Guide Information for advanced users can be found in our Advanced Usage Section, which contains details on the BaseX storage and the Server architecture, and presents some more GUI features. Categories: Internals You are invited to contribute to our Wiki: it's easy to get a new account. If you have questions and are looking for direct contact to developers and users, please write to our mailing list [3] ([email protected]). Main Page 2 References [1] http:/ / basex. org [2] http:/ / en. wikipedia. org/ wiki/ BaseX [3] http:/ / basex. org/ open-source/ 3 Getting Started Getting Started This page is one of the Main Sections of the documentation. It gives a quick introduction on how to start, run, and use BaseX. Getting Started • Startup: How to get BaseX running • Startup Options: See which command-line flags exist User Interfaces • Graphical User Interface: Working with the GUI (see available Shortcuts) • Database Server: Working with the client/server architecture • Standalone Mode: Working with the BaseX console on local databases • Web Application: Working with the HTTP server architecture General Info • Databases: Describes how Databases are created, populated and deleted in BaseX • Parsers: Describes how to convert different input formats to XML • Commands: Commands for managing BaseX and the databases • Options: Overview on all settable options Integration • Integrating oXygen: Use BaseX within the oXygen XML Editor • Integrating Eclipse: Use BaseX within Eclipse Startup 4 Startup This article is part of the Getting Started Guide. It tells you how to get BaseX running. Requirements BaseX Please download [1] the latest BaseX version from our homepage. The official releases include the BaseX JAR file, libraries and optional Start Scripts. If you do not use an installer, we recommend to manually add the project’s bin directory to your path environment; this way, you will be able to run BaseX from everywhere in your shell/terminal. Java A Runtime Environment of Java 1.6 [2] (JRE) is needed to run BaseX. BaseX is platform independent and runs on any system that provides a Java Virtual Machine. BaseX has been tested on Windows (2000, XP, Vista, 7), Max OS X (10.x), Linux(SuSE xxx, Debian, Ubuntu) and OpenBSD (4.x). GUI/Standalone vs. Client/Server The standalone client and the GUI of BaseX are not synchronized with other BaseX instances. If you plan to concurrently write to the same database instances, the client/server architecture is mandatory! You may encounter unexpected behavior, and your databases might even get corrupt, if you use BaseX instances that run in different Java VMs. BaseX GUI The GUI is the visual interface to the features of BaseX. It can be used to create new databases, perform queries or interactively explore your XML data. The GUI can be started as follows (get more information on all Startup Options): • Double click on the BaseX.jar file. • Run one of the basexgui or basexgui.bat scripts. • Execute the following command: java -cp BaseX.jar org.basex.BaseXGUI • On Windows: Double click on the BaseX GUI icon. • For Maven users: type in mvn exec:java in the main directory of the basex project. BaseX Standalone The Standalone Mode can be used to enter database commands, or execute automated database operations and queries, on command line. The standalone version can be started as follows (get more information on all Startup Options): • Run one of the basex or basex.bat scripts. • Execute the following command: java -cp BaseX.jar org.basex.BaseX • On Windows: Double click on the BaseX icon. Startup 5 BaseX Server The Database Server comes into play if BaseX is to be used by more than one user (client). It handles concurrent read and write transactions, provides user management and logs all user interactions. By default, the server listens to the port 1984. There are several ways of starting and stopping the server (get more information on all Startup Options): • Run one of the basexserver or basexserver.bat scripts. Add the stop keyword to gracefully shut down the server. • Execute the following command: java -cp BaseX.jar org.basex.BaseXServer. Again, the stop keyword will ensure a graceful shutdown. • On Windows: Double click on the BaseX Server icon, which will also start the HTTP Server, or the BaseX Server (stop) icon. Pressing Ctrl+c will close all connections and databases and shut down the server process. BaseX Client The BaseX Client interface can be used to send commands and queries to the server instance on command line. It can be started as follows (get more information on all Startup Options): • Run one of the basexclient or basexclient.bat scripts. • Execute the following command: java -cp BaseX.jar org.basex.BaseXClient • On Windows: Double click on the BaseX Client icon. The default admin user can be used to connect to the server: • Username: admin • Password: admin The password should be changed with the PASSWORD command after the first login. Please check out the article on the Database Server for more details. BaseX HTTP Server The HTTP Server gives access to the REST, RESTXQ and WebDAV Services of BaseX. By default, it starts an instance of the Jetty Web Server [3], which listens to the port 8984, and the BaseX Server, which listens to 1984. The HTTP Server can be started as follows (get more information on all Startup Options): • Run one of the basexhttp or basexhttp.bat scripts. Add the stop keyword to gracefully shut down the server. • On Windows: Double click on the BaseX Server or BaseX Server (stop) icon. • For Maven users: type in mvn jetty:run in the main directory of the basex-api project, and press Ctrl+c to shut down the process. • You may also want to deploy BaseX as a Web Application. Startup 6 Changelog Version 7.0 • Updated: the BaseXJAXRX has been replaced with BaseXHTTP References [1] http:/ / basex. org/ download [2] http:/ / www. java. com [3] http:/ / jetty. codehaus. org/ jetty/ Startup Options This article is part of the Getting Started Guide. It gives more details on the command-line options of all BaseX start scripts. BaseX GUI Launch the GUI $ basexgui [file] One or more XML and XQuery files can be passed on as parameters. If an XML file is specified, a database instance is created from this file, or an existing database is opened. XQuery files are opened in the XQuery editor. BaseX Standalone Launch the console mode $ basex

    Fun Factor: Coding with Xquery a Conversation with Jason Hunter by Ivan Pedruzzi, Senior Product Architect for Stylus Studio

    Fun Factor: Coding With XQuery A Conversation with Jason Hunter by Ivan Pedruzzi, Senior Product Architect for Stylus Studio Jason Hunter is the author of Java Servlet Programming and co-author of Java Enterprise Best Practices (both O'Reilly Media), an original contributor to Apache Tomcat, and a member of the expert groups responsible for Servlet, JSP, JAXP, and XQJ (XQuery API for Java) development. Jason is an Apache Member, and as Apache's representative to the Java Community Process Executive Committee he established a landmark agreement for open source Java. He co-created the open source JDOM library to enable optimized Java and XML integration. More recently, Jason's work has focused on XQuery technologies. In addition to helping on XQJ, he co-created BumbleBee, an XQuery test harness, and started XQuery.com, a popular XQuery development portal. Jason presently works as a Senior Engineer with Mark Logic, maker of Content Interaction Server, an XQuery-enabled database for content. Jason is interviewed by Ivan Pedruzzi, Senior Product Architect for Stylus Studio. Stylus Studio is the leading XML IDE for XML data integration, featuring advanced support for XQuery development, including XQuery editing, mapping, debugging and performance profiling. Ivan Pedruzzi: Hi, Jason. Thanks for taking the time to XQuery behind a J2EE server (I have a JSP tag library talk with The Stylus Scoop today. Most of our readers for this) but I’ve found it easier to simply put XQuery are familiar with your past work on Java Servlets; but directly on the web. What you do is put .xqy files on the could you tell us what was behind your more recent server that are XQuery scripts to produce XHTML interest and work in XQuery technologies? pages.
  • SPARQL with Xquery-Based Filtering?

    SPARQL with Xquery-Based Filtering?

    SPARQL with XQuery-based Filtering? Takahiro Komamizu Nagoya University, Japan [email protected] Abstract. Linked Open Data (LOD) has been proliferated over vari- ous domains, however, there are still lots of open data in various format other than RDF, a standard data description framework in LOD. These open data can also be connected to entities in LOD when they are as- sociated with URIs. Document-centric XML data are such open data that are connected with entities in LOD as supplemental documents for these entities, and to convert these XML data into RDF requires various techniques such as information extraction, ontology design and ontology mapping with human prior knowledge. To utilize document-centric XML data linked from entities in LOD, in this paper, a SPARQL-based seam- less access method on RDF and XML data is proposed. In particular, an extension to SPARQL, XQueryFILTER, which enables XQuery as a filter in SPARQL is proposed. For efficient query processing of the combination of SPARQL and XQuery, a database theory-based query optimization is proposed. Real-world scenario-based experiments in this paper showcase that effectiveness of XQueryFILTER and efficiency of the optimization. 1 Introduction Open data movement is a worldwide movement that data are published online with FAIR principle1. Linked Open Data (LOD) [4] started by Sir Tim Berners- Lee is best aligned with this principle. In LOD, factual records are represented by a set of triples consisting of subject, predicate and object in the form of a stan- dardized representation framework, RDF (Resource Description Framework) [5]. Each element in RDF is represented by network-accessible identifier called URI (Uniform Resource Identifier).

    Supporting SPARQL Update Queries in RDF-XML Integration * Nikos Bikakis1 † Chrisa Tsinaraki2 Ioannis Stavrakantonakis3 4 Stavros Christodoulakis 1 NTU Athens & R.C. ATHENA, Greece 2 EU Joint Research Center, Italy 3 STI, University of Innsbruck, Austria 4 Technical University of Crete, Greece Abstract. The Web of Data encourages organizations and companies to publish their data according to the Linked Data practices and offer SPARQL endpoints. On the other hand, the dominant standard for information exchange is XML. The SPARQL2XQuery Framework focuses on the automatic translation of SPARQL queries in XQuery expressions in order to access XML data across the Web. In this paper, we outline our ongoing work on supporting update queries in the RDF–XML integration scenario. Keywords: SPARQL2XQuery, SPARQL to XQuery, XML Schema to OWL, SPARQL update, XQuery Update, SPARQL 1.1. 1 Introduction The SPARQL2XQuery Framework, that we have previously developed [6], aims to bridge the heterogeneity issues that arise in the consumption of XML-based sources within Semantic Web. In our working scenario, mappings between RDF/S–OWL and XML sources are automatically derived or manually specified. Using these mappings, the SPARQL queries are translated on the fly into XQuery expressions, which access the XML data. Therefore, the current version of SPARQL2XQuery provides read-only access to XML data. In this paper, we outline our ongoing work on extending the SPARQL2XQuery Framework towards supporting SPARQL update queries. Both SPARQL and XQuery have recently standardized their update operation seman- tics in the SPARQL 1.1 and XQuery Update Facility, respectively. We have studied the correspondences between the update operations of these query languages, and we de- scribe the extension of our mapping model and the SPARQL-to-XQuery translation algorithm towards supporting SPARQL update queries.

  • JSON Application Programming Interface for Discrete Event Simulation Data Exchange

    JSON Application Programming Interface for Discrete Event Simulation Data Exchange

    JSON Application Programming Interface for Discrete Event Simulation data exchange Ioannis Papagiannopoulos Enterprise Research Centre Faculty of Science and Engineering Design and Manufacturing Technology University of Limerick Submitted to the University of Limerick for the degree of Master of Engineering 2015 1. Supervisor: Prof. Cathal Heavey Enterprise Research Centre University of Limerick Ireland ii Abstract This research is conducted as part of a project that has the overall aim to develop an open source discrete event simulation (DES) platform that is expandable, and modular aiming to support the use of DES at multi-levels of manufacturing com- panies. The current work focuses on DES data exchange within this platform. The goal of this thesis is to develop a DES exchange interface between three different modules: (i) ManPy an open source discrete event simulation engine developed in Python on the SimPy library; (ii) A Knowledge Extraction (KE) tool used to populate the ManPy simulation engine from shop-floor data stored within an Enterprise Requirements Planning (ERP) or a Manufacturing Execution System (MES) to allow the potential for real-time simulation. The development of the tool is based on R scripting language, and different Python libraries; (iii) A Graphical User Interface (GUI) developed in JavaScript used to provide an interface in a similar manner to Commercial off-the-shelf (COTS) DES tools. In the literature review the main standards that could be used are reviewed. Based on this review and the requirements above, the data exchange format standard JavaScript Object Notation (JSON) was selected. The proposed solution accom- plishes interoperability between different modules using an open source, expand- able, and easy to adopt and maintain, in an all inclusive JSON file.
